Description

박판 하우징을 포함하는 점성 댐퍼{VISCOSE DAMPER COMPRISING A SHEET METAL HOUSING}Viscous damper with sheet housing {VISCOSE DAMPER COMPRISING A SHEET METAL HOUSING}

본 발명은 하우징 및 커버를 포함하는 점성 댐퍼로서, 상기 하우징 및/또는 커버는 박판으로 제조되며, 상기 하우징 내부에 플라이휠 링이 가동 방식으로, 바람직하게는 유체 내에서 부동 방식으로 장착되고, 상기 점성 댐퍼는 베어링 홀을 갖는 것인 점성 댐퍼에 관한 것이다. The present invention relates to a viscous damper comprising a housing and a cover, wherein the housing and / or cover are made of sheet metal, and in which the flywheel ring is mounted in a movable manner, preferably in a floating manner in a fluid, The damper relates to a viscous damper having a bearing hole.

상기 방식의 점성 댐퍼는 공지되어 있으며, 특히 엔진의 크랭크 샤프트의 댐핑을 위해 사용된다.Viscous dampers of this type are known and are especially used for damping the crankshaft of an engine.

이 경우, 점성 댐퍼는 상응하는 샤프트 상에서 그 베어링 홀을 통해 센터링된다. In this case, the viscous damper is centered through its bearing hole on the corresponding shaft.

본 발명의 목적은 추가적인 센터링 가능성을 가진 상기 방식의 점성 댐퍼를 제공하는 것이다.It is an object of the present invention to provide a viscous damper of this type with additional centering possibilities.

상기 목적은 본 발명에 따라 하우징 및/또는 존재한다면 경우에 따라 커버에서 공통의 원주에 상에 놓인 2개 이상의 센터링 돌출부가 제공됨으로써 달성된다.This object is achieved in accordance with the present invention by providing two or more centering protrusions on the common circumference in the housing and / or the cover, if present.

상기 센터링 돌출부에 의해, 점성 댐퍼는 간단한 방식으로 베어링 홀의 직경을 보다 큰 직경에서도 센터링할 수 있고, 상기 센터링 돌출부에 의한 추가의 센터링 가능성이 주어진다.The centering protrusion allows the viscous damper to center the diameter of the bearing hole even at a larger diameter in a simple manner, giving the possibility of further centering by the centering protrusion.

각각 3개의 센터링 돌출부가 하나의 공통 원주에 놓인 실시예가 바람직하다.Embodiments in which three centering protrusions each lie on one common circumference are preferred.

기본적으로 2개의 센터링 돌출부에 의해서도 센터링이 가능하지만, 3개의 센터링 돌출부의 배치에 의해 센터링이 훨씬 개선된다. 이 경우, 상기 센터링 돌출부들은 서로 균일한 각도로 오프셋되어 배치되는 것이 바람직하다.Basically centering is also possible by the two centering protrusions, but the centering is much improved by the arrangement of the three centering protrusions. In this case, the centering protrusions are preferably offset from each other at a uniform angle.

3개보다 많은 센터링 돌출부의 사용은 개별적인 경우 바람직할 수 있지만, 반드시 필요하지는 않다.The use of more than three centering protrusions may be desirable in individual cases, but is not necessary.

센터링 돌출부들이 절삭, 스탬핑, 펀칭 등에 의해 형성되면, 특히 제조 기술면에서 매우 간단하다.If the centering protrusions are formed by cutting, stamping, punching or the like, it is particularly simple in terms of manufacturing technology.

리세스, 스탬핑부, 펀칭부 등은 방사 방향 및 접선 방향으로 연장되도록 배치될 수 있다.The recesses, stamping portions, punching portions, etc. may be arranged to extend in the radial and tangential directions.

본 발명의 다른 특징은 다른 종속 청구항에 제시된다. Other features of the invention are set out in other dependent claims.

이하, 본 발명의 실시예를 첨부한 도면을 참고로 구체적으로 설명한다.Hereinafter, with reference to the accompanying drawings an embodiment of the present invention will be described in detail.

도 1은 본 발명에 따른 점성 댐퍼의 부분 단면을 도시한 사시도.1 is a perspective view showing a partial cross section of a viscous damper according to the present invention;

도 2는 도 1의 Ⅱ 부분의 확대도.FIG. 2 is an enlarged view of part II of FIG. 1.

도 3은 도 1의 Ⅲ 부분의 확대도.3 is an enlarged view of part III of FIG. 1;

도 1에는 점성 댐퍼(1)가 도시되며, 상기 댐퍼는 공지된 방식으로 하우 징(2), 상기 하우징(2)을 폐쇄하는 커버(3) 및 플라이휠 링(4)으로 이루어지고, 상기 플라이휠 링(4)은 하우징(2)의 내부에 여기서는 유체 내에 부동 방식으로 장착된다.1 shows a viscous damper 1, which damper consists of a housing 2, a cover 3 closing the housing 2 and a flywheel ring 4 in a known manner, the flywheel ring 4 is mounted inside the housing 2 in a floating manner here in the fluid.

점성 댐퍼(1)는 중앙의 베어링 홀(5)을 가지며 상기 베어링 홀(5)을 통해 통상 암시적으로만 도시된 샤프트(6) 상에 센터링된다.The viscous damper 1 has a central bearing hole 5 and is centered on the shaft 6, which is usually only implicitly shown through the bearing hole 5.

본 발명에 따라, 도시된 실시예에서 커버(3)에는 센터링 돌출부(7)가 제공되고, 상기 센터링 돌출부는 샤프트 직경보다 더 큰 직경에서 점성 댐퍼(1)의 센터링을 가능하게 하거나 또는 샤프트(6)에서의 센터링에 추가해서 점성 댐퍼(1)의 센터링을 허용한다.According to the invention, in the illustrated embodiment the cover 3 is provided with a centering protrusion 7, which enables the centering of the viscous damper 1 at a diameter larger than the shaft diameter or the shaft 6. In addition to the centering in), the viscous damper 1 is allowed to center.

2개 이상의 센터링 돌출부(7)가 커버에서 공통의 원주 상에 제공된다. 물론, 추가의 센터링 돌출부(7)가 하우징(2)에도 제공될 수 있다.Two or more centering protrusions 7 are provided on a common circumference in the cover. Of course, an additional centering protrusion 7 can also be provided in the housing 2.

커버(3) 또는 하우징(2)에서 상이한 원주 상에 센터링 돌출부(7)를 배치하는 것도 가능하다.It is also possible to arrange the centering protrusions 7 on different circumferences in the cover 3 or the housing 2.

각각 3개의 돌출부(7)가 공통의 원주 상에 배치되는 것이 바람직한데, 그 이유는 이로 인해 센터링 돌출부(7)의 제조 비용과 센터링의 신뢰도 및 정확도 간의 매우 양호한 비율이 얻어지기 때문이다.It is preferable that each of the three protrusions 7 are arranged on a common circumference, because this gives a very good ratio between the manufacturing cost of the centering protrusions 7 and the reliability and accuracy of the centering.

센터링 돌출부(7)는 스탬핑, 펀칭 등에 의해 커버(3) 또는 하우징(2)의 영역에 형성될 수 있다. 센터링 돌출부들은 커버(3) 및/또는 하우징(2)에 방사 방향 및 접선 방향으로 연장되도록 제공될 수 있다.The centering protrusion 7 can be formed in the area of the cover 3 or the housing 2 by stamping, punching or the like. Centering protrusions may be provided on the cover 3 and / or on the housing 2 so as to extend radially and tangentially.

도시된 실시예와는 달리, 센터링 돌출부들(7)은 별도의 부분으로서 커버(3) 또는 하우징(2)에 고정될 수도 있다. 이 경우, 분리 가능한 또는 분리 불가능한 결합 방식을 선택할 수 있다. 예컨대, 별도로 제조된 센터링 돌출부(7)가 커버(3) 및/또는 하우징(2)에 나사 결합될 수 있다. 센터링 돌출부들(7)은 용접 또는 다른 결합 방식에 의해 커버(3) 또는 하우징(2)에 분리 불가능하게 고정될 수 있다.Unlike the embodiment shown, the centering protrusions 7 may be fixed to the cover 3 or to the housing 2 as a separate part. In this case, a separable or non-separable coupling scheme can be selected. For example, a separately manufactured centering protrusion 7 can be screwed into the cover 3 and / or the housing 2. The centering protrusions 7 may be inseparably fixed to the cover 3 or the housing 2 by welding or other engagement.

센터링 돌출부(7)는 경제적인 기준 하에서 스팸핑, 펀칭 등에 의해 박판으로 제조된 하우징(2) 및/또는 마찬가지로 박판으로 제조된 커버(3)에 형성되는 것이 바람직하다.The centering protrusions 7 are preferably formed on the housing 2 made of sheet metal by spamming, punching or the like and / or the cover 3 made of sheet material, on an economical basis.

도시된 실시예와는 달리, 다수의 센터링 돌출부들(7)이 점성 댐퍼(1)의 하우징(2)에서 상이한 크기의 직경을 가진 원에 형성되는 것도 가능하다.Contrary to the embodiment shown, it is also possible for a plurality of centering protrusions 7 to be formed in a circle with a different size diameter in the housing 2 of the viscous damper 1.

이로 인해, 본 발명에 따른 점성 댐퍼(1)의 사용 가능성이 증가된다. This increases the possibility of using the viscous damper 1 according to the invention.
